SPECIFICATION forming part of Letters Patent No. 575,040, dated January12, 1897.

Application filed October 3, 1895.

To @ZZ whom it may concern:

`Be it known that we, FREEBORN F. RAY- MOND, 2d, of Newton, in thecounty of Middlesex, and CHARLES H. Foce, of Hyde Park, in the county ofNorfolk, State of Massachusetts, citizens of the United States, haveinvented a new and useful Improvement in Presses, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specication, in explainingits nature.

The invention is illustrated as `provided with attachments or devicesfor compressing the heel of a boot or shoe, but it may be used for otherpurposes as well by substituting for said attachments such others as maybe necessary or desirable.

The invention will be described. in connection with the drawings,wherein- Figure 1 is a view in front elevation of a press having thefeatures of our invention. Fig. 2 is a view in side elevation thereof.Fig. 3 is a view in vertical central section of the Fig. 4 is a view insection upon the dotted line x of Fig. l and a plan of parts below saidline.

A is the frame or base of the machine. From its upper surface extendupward the rods a a a2 CL3. The lower ends of the rods are firmlyattached or anchored to the base. To their upper ends there is attachedby a collar and nut a stationary head B, the head having at each cornerholes through which the ends of the rods extend. This head supports theheelformer C, the heel-former being secured to a holder c, verticallyadjustable in the head by means of the adj usting-screw c', which screwsinto the holder and turns in the support or cap c2, rigidly secured tothe upper surface of the head, the screw having at its upper end ahand-wheel c3, by which it is turned. The frame A has in its uppersurface a bearing cl for the main shaft D of the machine, which issecured to the bearing by caps d', bolted to the top of the frame. Thisshaft carries a pressure-cam E of any required shape for compressingheels. That having the conguration in Fig. 1 is desirable. The cam iskeyed or otherwise firmly attached to the shaft D, and it provides thelower head Serial No. 564,493. (No model.)

F with an upward movement and permits it tomove downward. The head F isa solid block having extensions f at each corner, in which are holes f',through which the rods a a c2 a3 respectively extend, the rods servingas guides for the head. The movable head also supports a short stud orshaft f2, having a bearing in its under side at f3, to which it issecured by caps f4. This shaft carries a roll f5, which rests upon theperiphery of the cam E. The pressure-cam E preferably is shaped to movethe head F upwardly, rapidly at first, and as it approaches the pointwhere the greatest pressure is desired slowly; that is, the pitch of thecam is very much decreased, thereby increasing its compressing power oreffect, and this compressing-section is made as long as desirable, andthe cam is then reduced in diameter to permit the head to fall or returnto its original position.

The head supports the compressing dieblock G, which has a die-cavity gopening upward of the desired form for compressing the heel-blank and issupported upon a plate'g, mounted on the top of the movable head, beingfastened in place by the buttons g2, which button onto the top of thedie-block. The die-block also has a forward-extending section gwhich hasside guides or walls g4,which extend backward on each side of thedieopening, and the die-block is inclined upon its-top and rear cornerat g5. The extension g3 and guides g4 form a support andv road or guideway for the heel as it is fed to the die. The section g3 supports theheel. The guides or walls g4 prevent it from turning. The heel isadapted to be automatically fed to the die and to be automaticallydischarged from it. Itis held stationary after the compressing action bythe plate H, which forms the bottom of the die during the compressingaction and which is at the upper end of the post h. After the head F hasbeen moved upwardly to some extent the plate g comes into contact withthe plate H, which then is in the bottom of the die, and moves itupwardly, and when the head F moves downwardly the post h comes incontact with a cross-bar 7L', extending from and supported by the postsh2 on each side of the movable head through a hole h3 in the IOO head,and is thus brought to a rest, while the headF continues to movedownward, and this causes the die to strip itself of the heel, the heelat the end of the downward movement of the head and die, occupying aposition in relation thereto represented in Fi 3, being about on a levelor a trifle above the level of the upper surface ofthe die. The machinemay have a stopmotion to stop it af tereach reciproca-tion of thehcad,orit may be run continuously. It is represented in the drawings asin the latter form, and the heels are automatically fed bybeing placedone after another upon the heel table or support g3 in front of thepusher M, when in its outer position. This pusher is reciprocated towardand from the die-cavityin the space between the two walls or guides y",and it has a central arm m, which extends through a clamp-holder m',pivoted at m2 to the upper end of the lever mg. The clamp-holder has aclamping-screw ou, which fastens the arm or spindle m in any desiredposition and thereby permits the pusher to be adjusted to dies and heelsvarying in length. The clampholder is held down at its forward end by aspring m5, connecting it with the lever mi. The lever m3 is pivoted atm13 to a bracket m12, attached to the slide-head F, and has a short armon, to which is pivoted at mi? a sliderod m8. The slide-rod is supportedin a forward extension m of the bracket mit, and it carries at ils lowerend a cam-roll m10, which bears upon the edge of the cam in at the frontend of the shaft D. This cam is so shaped as to move upward theslide-bar m8 and thus move inward the lever M3, which causes the pusherM to be moved upon the support g3 between the ways g4 and push or feedthe heel along the roadway to a position upon the plate ll and over thedie-cavity, and at the same time the heel then beingfcd acts to dislodgefrom the plate Il and push off it and the die-block thepreviously-compressed heel; y

The main shaft D is rotated by the gear N, keyed to the shaft and withwhich a pinion n upon a shaft a engages. This shaft n is mounted in thebearings 'n2 at one side of the bed or frame and is held therein by thecaps a3, the pinion being at the back end of the frame, and this shaft nalso carries beyond the pinion the gear ai, which is in turn engaged bya pinion a5, which is loose upon a rearward extension of the main shaftD, the pinion having a long hub a, to which the bala'nee-wheel N isattached, the balance-wheel and pinion thus being loose or free upon theshaft D and communicating' rotation first to the gear a and shaft n",and then b y the pinion `n on shaftf/r to the gear N, fixed on the shaftD. At the rear end of the shaftD is a loose pulley a7, upon which thebelt may be run and which turns freely upon the shaft withoutcommunicating movement to it. The advantages of the invention arise fromthe simplicity of the construction, its strength and power. XVe preferthat the support g3 and guides g4 be cast with the die-block G, but thisis not essential.

\Ve would call attention to the following peculiarities in the operationof the machine: The heel-pusher rests upon the heel-support and travelsupward and downward therewith. lt is not moved inwardly, however, topush a heel upon the plate ll until the head F is in its lowest positionand stationary upon the rest of the cam, the head thus remainingsufficiently long to permit the pusher to feed the heel upon the plateII. It is obvious that an uncompressed heel cannot be used for removinga compressed heel until the bottom of the compressed heel is upon alevel with or slightly above the upper surface of the d ieblock. It willfurther be seen that the pusher and its operating devices, excepting thecam, are carried by the head F and move upwardly and downwardly with it.A spring fm 'may be used for moving the push-bar ms downward] y an ddrawing forward the heel-pusher. The support g3 has a central slot orrecess opening from its front end into which the upper end of the leverm" is moved as the pusher is thrown inwardly in feeding a heel. The heelis fed by the pusheralong the roadway or feedway between the guides orwalls g4 to the upper surface of the plate II when the die-block is inits lowest position,(see Fig. 3,) the upper surface of the die-block atthat time being substantially upon the level of the upper surface of theplate II. It will be 1111- derstood that in the operation of feeding aheel to the die, compressing the heel, stripping the heel from the die,and removing the compressed heel the die-block and the plate Il havesubstantially these movements: The heel to be compressed is placed inthe roadway in front of the pusher M, when it is in the positionrepresented in Fig. Rotation of the cam in moves the slide 'm8 upwardlyand causes the pusher to be moved inwardly, feeding the heel along theroadway to the upper surface of the plate II and dislodging from theplate II the previouslymolded heel, which slides down the incline g5upon the die-block into a conveyer or rceept-acle4 (Not shown.) Thepressure-cam E meanwhile has been revolving, but simply serves to holdthe pressure-head F and the die-block stationary, the roll f5 then beingupon a rest of the cam. When the heel is in position upon the plate Il,the cam E begins to move upward the head F, causing the diecavity toclose upon the plate Il and the heel, and this movement continues untilthe plate g/ comes into contact with the under surface of the plate IIand the heel-blank has been partially received into the die-cavity, whenthe die-block and plate H and heel are lifted together to the stationaryheel-seat former C and the heel-blank compressed or molded and theheel-seat formed in the die-cavity. Preferably the first portion of theupward movement of the head F and die-block is relatively rapid, whilethe latter part of the movement IOO IOS

during the compression of the heel is slower. This permits thepressure-cam E to be used to its best advantage.

Upon the completion of the molding of the heel the pressure-cam, stillrevolving, is constructed to permit the head F, the die-block, and thecompressed heel to move downward from the former C, and during thisdownward movement the molded heel is stripped from the die by causingthe plate l-I to come to a rest or stop by the coming in contact of itsstud 72, with the bar 7L', while the head F and the die-block continueto move downward or to the position represented in Fig. 3, and thisserves not only to strip the molded heel from the die, but also to bringthe plate H into position to receive the next heel to be compressed.`The head F is heavy, and its weight is sufficient to cause the die tostrip from the heel and the cam-roll f to maintain its contact with thepressure-cam E during the downward movement. The heel-pusher M and allits operative parts, except its operating-cam', are movable upwardly ordownwardly with the head F, and its slide-bar m8 is separable from theactuating-cam m11, the cam having a section which operates upon thepusher only during a portion of its revolution, and the pusher beingwithdrawn after the operation of the cam in feeding the heel to theplate H by the spring m14. This permits the pusher to begin itsmovement, if desired, before the head F has reached its lowest position,and also permits it to be withdrawn after the head begins to lift. Thepressure-cam E is constructed to have a very slow rise during thecompressing of the heel that it may deliver a great pressure during themolding operation.

Having thus fully described our invention, we claim and desire to secureby Letters Patent of the United States- 1. The combination of the bed ofthe machine, the upwardly-extending rods, the stationary head D, themovable head F guided by the rods and having the cam-roll f5, the shaftD having bearingson the bed and eX- tending backwardly therefrom, thegear N fast to the shaft, the shaft n" having bearings in one side ofthe bed, the pinion n fast thereon and engaging gear N, the gear n4 onsaid shaft n', the pinion 015 having a bearing on an extension of thelshaft D and meshing with the gear n4, and a driving or fly wheel free onsaid extension of shaft and connected with the pinion 715 to rotate itupon said shaft extension, as and for the purposes described.
